A winding fire-road hike to one of the front peaks near the Mt. Baldy Area. This is the longer but less strenuous of two routes, and offers outstanding, panoramic views of the Baldy Bowl and – on clear days – the seemingly never-ending sprawl of Rancho Cucamonga. At the peak itself are the remains of an old fire tower that burned down years ago.
The Basics:
- Distance: About 7.8 miles
- Elevation Gain: About 1300 feet
- Time: A little over 3 hours — probably less time if there’s no snow or ice on the trail.
- Trail Condition: Very good. It’s fire road almost all of the way, so it’s wide and relatively level. Junctions aren’t marked, but just keep going up and you should be fine.
- How To Get There: Take the 210 to the Mount Baldy exit. Continue north toward Mount Baldy Village, then turn left onto Glendora Ridge Road. Drive about 4.2 miles past Cow Creek Saddle to a turnoff on the left hand side of the road. Park here, display your Adventure Pass, and start your hike on the Fire Road.

The Notables:
- Relatively easy fire road trail
- Excellent views of the Baldy Bowl, San Antonio Canyon, and Rancho Cucamonga.
- Remains of a fire tower at the summit

The skies were still clear and the weather was still cool from our recent rain. I wanted to add another peak to my Hundred Peaks Section list and also get a good, up-close look at some snow-covered mountains instead of the more distant vistas I had back at Temescal, so for this hike I headed back east to the Baldy Bowl.
The Bowl may be my favorite hiking area in the entire Angeles National Forest. Sure, there’s the prominent namesake peak, but there are also the impressive “Three Tees” – Timber, Thunder, and Telegraph, the twin sentinels of Cucamonga and Ontario, and many more miles of wilderness trails on the north side of the mountains. For this trip, I set my sights on the least tall of the Baldy Bowl Peaks — Sunset Peak.
Located on the western side of San Antonio Canyon, Sunset Peak promised to offer some great views of both the mountains and the cities below, and — with the recent precipitation we’ve been blessed with — some snow-covered alpine scenery, too. From the exit off the 210, I could already see that Ontario Peak had a healthy dusting.

Unfortunately, it didn’t look like I was the only one attracted to the snow that day. The closer I got to Mount Baldy Village, the more congested traffic got — not exactly the thing you look for when you’re driving that far away from Los Angeles. But instead of continuing toward the ski resorts, I turned off onto Glendora Ridge Road, passed the first trailhead at Cow Creek Saddle, and pulled off the road near a Forest Service road.
The view from the trailhead was already impressive — as the Sprawl Cities lay to my south and Lookout Mountain and a large chunk of Baldy guarded the north. If you look closely, you can see the wind whipping some of the snow off the top of the peak.

The trail is on this Forest Service road, which slowly and deliberately winds its way to the summit. While I was hiking up, I didn’t pass anyone but did see several hikers’ trails in the small bits of remaining snow, along with a fair share of dog and horse tracks.

While the trail itself was not very interesting, the views were outstanding. Like I mentioned before, the rain gave some (sadly) artificially huge visibility ranges — I could make out peaks as far west as Mount Wilson and the bat-ears of Strawberry and Josephine.

The trail starts off at the end of the scrub range, and as it winds its way up, starts to move through the Jeffrey Pine in the higher elevations. It’s one of the shortest and easiest ways to experience one of the major landscape shifts in the Angeles National Forest.

Most of this trail is on the north face of the mountain ridge, which means it’s more shaded and generally cooler than the rest of the nearby terrain. For me, this meant I was trudging through snow for most of the way up. And not the fun, powdery stuff, but the crusted-over, tough, icy snow. It wasn’t too bad, but it did decrease my hiking speed a bit.

At about the 3.6 mile mark, the trail circles around a small ridge just to the northeast of Sunset Peak’s summit. Here, the fire road meets up with a small firebreak / use trail that ascends from Cow Creek Saddle. It is an alternate route to the peak, but is much, much steeper than the fire road route I describe here. I would have taken it, had it not been completely iced over. Steepness and ice are not two things you want to mix if you don’t have the proper equipment.
Instead, I took in the views from this area, which encompasses a nearly 360 degree view of the San Antonio Canyon and Baldy Bowl. The view from the actual peak will be better, but this is still pretty impressive when you first lay eyes on it. The long, sloping ridge of Baldy dominates to the left, with Thunder, Telegraph, and Timber in the center, and the north slope of Bighorn on the right.

From there, it’s just a short (or, very short if you take the use-trail) trip to the summit of Sunset Peak. The fire road swings around to the south of the summit and continues away from the peak. Here, there is a very easy-to-spot trail that will take you north toward the summit, where you can fully get that full 360 view you’ve been longing for — as well as spot a few leftovers from a burnt-down lookout tower that used to crown the peak.

That looks like a fantastic place for a hike. Those are some really nice pictures. I have never been out that far west, as I live in Michigan, but I will certainly check this place out when I can get out in that area.
You might be interested to know that Sunset Peak was part of an important experiment in 1926 by Albert A. Michaelson to determine the actual speed of light. Using rotating mirrors he was able to measure the time it took light to make a round trip from Mt. Wilson to Sunset Peak. The precise measurements yielded a speed of 299,796,000 m/s. The concrete pillars you saw on the peak were part of the support structure for the experiment.
That is a fascinating piece of info, Kelly! Thanks for filling us in on the details!
Actually, the 1926 Albert Abraham Michelson Speed of Light experiment was conducted at Lookout Mountain, 2.33 miles to North-East of Sunset Peak.
How long is this trail? Is it really 3.6 miles where it meets cow creek sadle? I just mountain biked this trail yesterday and was curious.
Great write-up and video about Sunset Peak. I’m headed there tomorrow and this was sure helpful. Am going the shorter, steeper route on the way up, then taking the fire road down.
Great hike, especially for beginners. The view offers great peace and tranquility. If you have a large dog its also a great place for them as well. Also saw a few bear tracks, but no worries they were days old. Great pics, nice job, thanks….
JUST HIKED THIS TRAIL YESTERDAY & IT WAS THE PERFECT DAY FOR IT. BEAUTIFUL VIEWS. HIT SNOW ON THE TRAIL ABOUT 1 MILE INTO THE HIKE. BOOTS A LITTLE WET BUT IT WAS SUCH A WARM DAY I NEVER FELT IT. SHORTS & TANK TOP THE WHOLE WAY.
Tried to go there last week but Glendora Ridge Road was closed about 1 mile W of Mt. Baldy Village. Ranger said it would be closed “For a while.” Guess it’s already open? I’ll have to try, again.
Instead, I did the Potato Mountain hike.
Hiked this one today. OUTSTANDING views from the summit, even though clouds were obscurring the taller mountains. Still a fair amount of snow on the fire road where the north-facing slopes shades it.
The gate across Glendora Ridge Road was open, so I drove the 3.2 miles more to the intersection with Forest Road 2N07, and followed this road up. It’s just before mile marker 7.75.
However, afterwards, when I stopped by the Mt Baldy visitor center, the ranger said this road (Glendora Ridge Road) was supposed to be closed. Also, in looking carefully at the maps available, it seems road 2N07 crosses over a bit into the San Dimas Experimental Forest, so you should need a permit. However, the USFS flyer shows the road as a valid way up (assuming Glendora Ridge Road is open that far). I don’t get it.
The ranger also said that, since Glendora Ridge Road was supposed to be closed, the “proper” way up Sunset Peak was to take the shorter, steeper route from Cow Canyon Saddle. However, the USFS flyer has what looks like a “Do Not Enter” symbol over the part of the fire road 2N07 that approaches from that side. It does not indicate the trail at all, although a trail seemed apparent from the ground and from the top of the knoll where the trail joins 2N07. Also, it indicates “Parking” in the big clearing on the north side of the road, where, in real-life, there are “No Parking” signs all around. The only legal parking at this junction is on the south side of the road, and that only has room for two or three cars. On a weekend, you’d have to park further down Glendora Ridge Road and walk back up to the junction.
There’s room for a lot of cars at the other end of 2N07. But, as noted earlier, that part of the road is “supposed” to be closed. Again, I don’t get it. I don’t think the state, county, or city highway folks who work on this road and the USFS are communicating very well.
Ooops. Where I wrote “Cattle Canyon” above, that should say “Cow Canyon.”
